16GB Class 2 or Class 6 ?

I am not quite sure about this..
The Class 6 is 40% more expensive than class 2 ... But which one is better for my HD2 ?
Is class 6 will worth it ? any tech glitch if I use class 6 (maybe too fast ?)
Thanks

I dont think its woth it. but its a bit faster. if your budget allow you go for it

I think class 4 is the best of both worlds...
class 2 maybe too slow on saving something like a long video u shoot with your cam and i think that class 6 doesnt worth its money.. i have a 8gb class 4 and im really happy with it..

I have a Transcend 16GB Class6 and it is especially fast when use HD2 as "storage memory" or when insert the microSD directly in to my PC.
During the normal use probably a Class 4 is ample.
Regards

Class 2 is more than adequate. Your card is only as fast as the writer/reader hardware.
Food for thought: The majority of 16Gb MicroSD failures with the HD2 have been Class 4 (me included - I had a 2 month old Sandisk Class 4, 16Gb fail on me in this phone, bought a new Kingston Class 2, 16Gb and have not had a problem)

Obviously, yes. But I have no problem at all with my microSD Transcend 16GB Class6 on my Leo HD2.
All works fine and fast. And the hardware reader/writer on the HD2 is used at maximum of it's performance
Regards

Class 6 is too expensive. I got the Sandisk 16GB uSDHC Class2 and it's fine.

same here, working perfect

Same with me!

I disagree with most guys in here. considering that you have just spend a hell lot of money on the HD2, I think that you might as well spend a few more bucks on a class 6 card, than a class 2. Especially considering that micro sd cards are so cheap today, I see no problem in that tiny bit of extra cost.

Class 6 value?
Of course it's worth it.
Copying, TomTom, photos, are all faster.
I don't believe Sandisk make a class 6 16g

It is important to note that using a class 6 rather than class 2 card will make absolutely no difference whatever to the performance of the phone - the phone itself is unable to read from or write to the card any faster than a class 2 card can easily cope with. The only time the class of the card makes a difference is if you take it out of the phone and plug it into a card-reader attached to a desktop PC.

Surely this phone can read faster than that? Seems odd that a high spec phone like this can't read faster than a class 2 card.

could somebody test class-2-4-6 cards in hd2? I'm curious to know what should I buy.

The difference between class 2 and 4 is noticable to me on the HD2, so a class 6 would be nice, but so hard to find.

Well, you have to ask what the phone might be doing that would actually require data to be read or written that quickly. If you're watching a video, for example, the highest bit-rate you'll encounter will be 2 to 3 Megabits per second. Even the worst class 2 cards can be read at 3+ Megabytes per second. So you certainly won't get smoother video playback with a higher class of card. The camera doesn't take pictures quickly enough for the data transfer rate to the card to become a limiting factor. What might you be doing that needs more than class 2 speed? Given that you don't need more than class 2 speed, it would be a waste of money to enable the phone to read or write faster than that.
If you don't believe me, try running an SD card benchmark on your phone, and let us know the results.
The class ratings tend to be quite conservative, in fact, especially on name-brand cards. You can easily read at 8 or 9 MB/s off a "class 2" card from Sandisk (indeed, it may even outperform a no-name "class 6" card). That's more than enough speed for the phone.

One GREAT WAY to speed HD2 PERFORMANCE

I created videos showing the dramatic difference (before vs. after) but then realized this site does not allow me to upload videos (and I am too lazy to set up a utube account).
The 16GB Micro SDHC card that comes with the T-Mobile HTC HD2 is only Class 2 and is a very SLOOOOOWWW card (also class 2 cards are CHEAP, that is why it is INCLUDED FREE). If you watch the Transformer movies installed on that card you will discover there are a few times during the movies where the screen momentarily freezes. Also if you have alot of songs on the card, when you scroll over to the media player you will see it takes forever for the media player tab (about 45 seconds) to display anything. Even a game that comes with the unit repeatedly freezes and is not playable because of the speed of the card - under games, try the game called "Ferrari GT Evolution". It is a great game but it is unplayable on that card.
I purchased a 16GB Class 6 Micro SDHC Card and it came today. I copied everything from the old card to the new card. WOW, WHAT A DIFFERENCE! It is about $60 but is makes a VERY big difference in performance for everything mentioned above. For instance, the Ferrari game mentioned above does not freeze at all (and loads much faster) and also when I scroll over to the media play tab the delay before that tab becomes useable is only about 3 seconds.
If you want a SAFE great way to really improve the performance of your unit, replace the old crappy Class 2 Micro SDHC card with a Class 6 version. WOW.
(BTW, my main reason for getting this card was also that it took too long to take a photo and then to be able to take another one immediately afterwards. Now that is MUCH faster as well. A workaround would be to not use the card for picture storage but I prefer to put them on the card.)

I have been using a 4GB class 6 card I had laying around and I have seen a difference as well. I copied all the data from the 16GB card to my computer then copied it to the 4GB card to start out with. I saw a big improvement in the momentary freezes that occur when navigating the UI, music indexing and video playback. After using that card for a couple weeks I copied everything back to the 16GB card after formatting it and popped it back in to see if it was a placebo effect. Things were noticeably different, it just felt more sluggish at times. The Class 2 card isn't bad and it isn't the whole problem but getting a better card does change things a bit.
I did pick up a couple 8GB class 6 Sandisk cards for about $10 not to long ago for my camera. The 16GB and 32GB cards aren't as economical yet. The improvement is worth $10-$20 dollars to me but not $60.

how can i tell if my other card is a class 4 or not

It'll be printed right on the front of the card...a little number inside of a circle. If you dont see one there, odds are it's a class-2

Panasonic makes a Class 10...that's what I use lolol...

Class 6 vs 2 Photo... (Micro SDHC Card)
There is no such thing as a Class 10
Look at the photo (CLICK ON THE PHOTO TO ENLARGE IT AND SEE THE DIFFERENCE) FOR THE Speed Class Designation. I guess the standard spec does not say which way is right-side up for printed labels!
Class 6 is the highest speed currently. There are 32GB cards out there (which the unit can support) but they are VERY expensive. The Class 6 card I bought was somehyting like $60 with the shipping from Newegg.com.
Also notice that it is such a damned nightmare to be able to read these ever so tinier labels on everything out there! (Or maybe it's also because of my age.)
It is true, also, that those without the class specification are much older - and slower, I guess they should all be lumped in presumably with class 2

$100...Hope they become cheaper!

thanks for this thread... i totally didn't realize there were speed diffs on microSD cards.
so a few questions then:
1. the new 32GB sandisk microSD is only class 2... i assume no other manufactures are out yet, especially with a class 6 or 10. this is the very end of the SDHC standard. the next upgrade will be all SDXCs.
2. will a class10 be better than a class 6? i always thought that there are spec. limitations to SD card readers itself. does anyone know what the max limit of the HD2 SD card reader is? class 6 or 10? because if it's class 6, then buying a class 10 would be useless.
i remember that older SD card readers can't read the SDHCs.

1. I haven't seen any class 6 32gig cards but there will be some eventually.
2. Technically class 10 is faster than class 6 but unless you run everything off your sdcard and have a ton of music/video I doubt it would be worth it. If you were going to be using a 32gig card then a class 10 would probably be worth it, though I don't know if the HD2 supports that speed.

Thanks for the "usual" lolol...
To be honest I've got the class 10 Panasonic, and a class 6 Kingston, (both 16gb [32gb models are ridiculously expensive]) and when you run them side-by-side in a phone, there really isn't a difference in everyday use that I can tell. Class 6 is plenty fast for a phone. But there's always people like me in the world who aren't afraid to fork over the extra money to see if the latest tech will get me a little extra speed.
For those on the ropes as to what to get: if your just listening to music, Class 2 is good; for video, class 4 is good; if your non-stop music and video all day everyday work and play, and have some extra cash Class 6 rocks.
For all of you nut jobs like me who care about the extra microseconds of speed, lolololol, and have the money to spend...get the Class 10...
~Jasecloud4

the first thing i did for my hd2 was upgrade to a class 6 from previous experience with rooted android handsets (where upgrade to class 6 is always recommended

would a class 10 or a class 6 improve battery life?

Thanks for the thread and the informative posts, I guess I will make sure to get at least a class 6 for my media heavy device.

Also, if I were to buy one, which companies are reliable? Or are they all pretty much the same? I've only heard of SanDisk and Kingston because I've met the co owner of Kingston and he gave me some free stuff before.

I would just stick with sandisk or kingston anyway, they're both as reliable as any, and usually priced right along the lesser-known maufacturers.

So for anyone who has used both a class 6 and class 10 card IN THE HD2, is there a speed difference? I have a paypal coupon code that is good for 25% off, and am eyeing some of the class 10 kingston cards on ebay which would come out to about $74 with this coupon code. Not very much more than a class 6, course i could just use the coupon code for a class 6 off ebay too. I would like to go the 32gb route, but seems everything 32gb is class 2 =(

Has anyone tried a Class 6/10 MicroSDHC card?

Found some Transcend and A-Data class 6 MicroSDHC cards that are sold cheaply on Amazon, but I'm not sure I want to spend the extra cash if the Evo has bottlenecked write/read speeds. So I was wandering if any of you have tested out a class 6 or 10 MicroSDHC card on the Evo.
The Evo comes with a Class 2 card.
Download "SD Card Speed Tester" from android market to base our results. Will be posting mine in a bit.
First test results for 8GB Class 2 MicroSDHC Card(Comes with Evo):
Write speed is 2.0MB/s
Read speed is 9.0MB/s
Second test same card:
Write 4MB/s
Read 9MB/s
Well I read that this test is inaccurate. I will try to find better, external methods.
Does the Geebees matter when it comes write/read speeds on SDHC cards?

I bought a 32GB class 6 from ebay. took a few weeks to get since it came from hong kong and i paid 40 bucks :] anyways, writing to the sd seems smoother to me. i havent "truly" tested since im a complete n00b

without any "real" tests in android there really doesn't seem much of an improvement. mainly b/c the small amount of data that apps use.
nandroid back ups are faster though and prepping sd card at boot up is faster.
no numbers though.

Oh please do, can't test it, don't have a class 6 card. Hope some people who do stumble onto this thread.

I bought a 16GB Class 6 mSDHC card and I can tell you that it is noticeably better than the shipped 8GB Class2 card. I notice it most when playing back high bitrate vid, I ripped some stuff from blu-ray to 800x480 mpeg4 and it loads the video faster now and plays without a single hiccup. Also from time to time I would get hiccups in the 720p videos recording with the class2 and I have not had a single hiccup with my class 6 card.
These are just my observations I have no actual measurements to compare so take this with a grain of salt.

Sorry, confused myself with the standard SD.

I just ran that SD speed card test, transcend c6 card. Not using a2sd or anything else. It reports write speed at 5MB/s, read at 10MB/s. Says its a c4 card. Dont know how accurate the test is but thought itd be useful posting...
*edit* ran it a second time and got write at 5, read at 11. Seems pretty consistant

Test multiple times, for some reason I got 4MB/s write the second time.

ran test a 3rd/4th time.
Write 6MB/s
Read 10MB/s
Write 5MB/s
Read 11MB/s
A fluctuation of a meg up or down i think is normal. The program might also round seeing i saw no partial numbers. Now as far as if its worth it to get a c6 id say yes regardless just for the wearleveling features.
from cyaogen wiki: http://wiki.cyanogenmod.com/index.php/Swap_and_Compcache
However, newer, high-end SD cards feature wear leveling, a mechanism that distributes write wear uniformly over the entire memory card by dynamically remapping logical memory blocks to different physical memory blocks over time. This largely alleviates the issue of card wear when using applications that tend to write to the same memory blocks over and over (i.e. swap). Most Class 6 microSDHC cards include hardware wear leveling, while Class 4 and lower cards typically do not. This feature depends on the decision of your card's manufacturer. A-Data and Transcend Class 6 cards were specifically cited as having hardware wear leveling.

I have a 16GBA a-data class 6 in mine and the speed test is showing 8mb write and 12mb read. Not sure how accurate that is though, the read speed is about 4mb faster than what my computer told me it was.
A-data cards are fast but if you get another brand make sure other people are saying they can do what they say they can. There are a lot of companies who flat out lie.

I seem to have gotten lucky with my Class 2 16GB.

Make sure you test it thoroughly before you run out of time to file a claim. There have been a lot of 16gb cards with the 32gb markings coming from china. It's formatted so it looks like the space is there but they wont let you use more than 16gig

Actually alot of the cards on ebay at 2gb cards. Not even a full 8 or 16. Also if you want to do a better test for your sd card speads use ATTO. its free and gives alot better breakdown. It runs on your PC.

Anyone using a class 10 card?

Hey. Just curious how many of you have replaced the stock 16gb class 2 sdcard with class 4,6 or 10. Can you chime in with your inputs on performance between these classes. I know the theoretical transfer speeds, but I am curious how they actually perform in day to day use. Would jumping from a class 2 to class 6 be noticeable, or a class 6 to class 10?
Thanks

I am interested to.
Have just upgraded to an Ebay 16gig Class 6. Speed is faster than a Class 2 but not sure if it is a Class 4 or class 6.
Tempted to buy a 8gig Class 10 but struggling to find a reputable source of these.
In case you don't know Class x denotes the write speed. Class 2 has a 2meg/sec. Class 6 has a 6meg/sec write speed. Also gt a increase in read speed. All must be good for the HD unless the Interface is slower than the card??

From my reading and investigation, not many devices out there support such high speed, I'm thinking phone isn't one of the device that do. I would like to see someone do some testing and see if there is a difference on a HD2 between a class 6 vs class 10.

I didn't know they had a class 10, but I'm running a class 6 and I can tell the difference from the 16gb stock card. Loading Android is a lot faster too.
Sent from my HTC HD2 using XDA App

I have a class 10... Its a great diference.

I've got a couple of 16Gig class 2s and a 4Gig class 10. I can certainly tell a difference. I haven't done any empirical testing but gut says it's almost twice as quick. The difference comes when you multitask, getting a couple apps open, app loading, etc.
The problem with the 4Gig is the obvious lack of size. I'm thinking of buying a 32Gig class 4.

Looking at numbers alone, a class 6 is three times faster than a class 2 and a class 10 is five times faster than a class 2 so upgrading from a class 2 would appear to be a sure fire bet in both cases
In comparison a class 10 is only 1.6 times faster than a class 6.
So I think I will stick with my class 6 for now until class 12+ comes out.

So in conclusion do you guys think a faster SD card is necessory? because once xda team finish develop a perfect android rom i believe they are gonna make it a rom, in that case we would'nt need a faster SD card, But i really wonder if a faster SD card improves the performance? Can someone kindly provide a video for this ? Thanks ,,

class 10
I have a 16gb kingston class 10, compared to my Transcend 8gb class 6, not that much difference, compared to my Class 2 16gb that came with the phone? huge difference.

I'm now going out, to buy a 16GB classe 4 , i think is sufficient, given that in September Cttula will provide NAND, and the class will no longer important, and I'd rather have more space for my photos and videos, in vacation than a business card 8GBclasse10 faster.

Is the ETA for NAND September?

Nand speed vs. Class 10 card?
Anyone know what the read/write speed of the nand memory is as compared to the say the read/write speed of a class 10 card? I know it should be faster, but is it really that much faster?

transfers between pc and phone is up tp 6 mb/s read and write, but on the phone it self i think it's faster.
previously i had class 2, 8gb sandisk and it was alot slower...

how do I know which class the SD card is?

i use a class 10 card in my digital slr and it makes quite a big difference. i'm sure it would create a significant performance boost with android

SD Card Class

Dear xda-community,
a simple question: Which classes do you consider reasonable and which are overkill? Class 2 , 4 , 6 or 10?

There are only very small differences in real-world performance in MicroSD cards no matter what class they are (unlike "normal" SD cards). Even a class 2 will give no problems with HD video recording. I've got a 16 GB Sandisk Class II. Cheap. No problems. What more could we want?

Agreed...
Phone's do not have great demands on memory cards, not even when writing at the highest video frame rate.
I have quite a few Micro SD's to choose and use.
Although I'm using a Sandisk 16GB Mobile Ultra which has a Class rating of 4, in real tests it performs much much faster but is quite really overkill for the Phone.
My recommendation, don't get a cheap Class 2 but go for a solid & reliable card.
It's worth paying that little extra on say a Sandisk Class 2 than a low rated unbranded Class 4/6.

Dear xda-community,
a simple question: Which classes do you consider reasonable and which are overkill? Class 2 , 4 , 6 or 10?

i use class 6
class 10 is probably over kill
don't buy anything less than class 4

Okay, so i suppose i'll get a class 4 or 6 card, depending on the current prices.
Thanks for your help

As I have already mentioned it's not so much the class rating that matters but more the quality of the card.
The matrix of the Galaxy S's buffer run does not need anything great.
As such a reliable Class 2 would suffice.
As an example the Sandisk 32GB Class 2 easily provides acceptable video frame rates.
I recently ran this card and my present Sandisk 16GB Mobile Ultra card and visibly there was no difference in both saving camera video's or showing either a camera video or movie.

Why? Please let me see some benchmarks that can convince me there is any idea in buying a class 4 instead of a class 2.

So, just buy a cheap 16 GB Sandisk class 2 - anything else will be a complete waste of money.

Again agreed.
The answer here is in the name Sandisk.
MoWa22 also fully understands and appreciates it's the brand what delivers and not so much the Class rate.
Sandisk cards often perform much faster than their same class counterparts.
Good link btw.

Class 4 or 6 is what you need class 2 is to slow.. you will notice the different between at class 2 and 4 in your phone go with 4 or 6 anything higher is over kill.
